You could have a look at poller graphs before and after and see if some modules are taking longer etc.

Or you could just adjust your worker count up if your host has spare CPU/disk io cycles.

Do you have rrdcached configured as that can help substantially if disk IO is high?

the problem is after upgrading poller module graphs not showing up like image attached

I have the same issue, did you resolve it ?

Are you using cron polling or the SystemD service?

using crond polling yes

still not fixing it
